Best Alternatives to Together Link in 2025
Together Link lets you use open models in your existing coding harness, connecting agents to Together AI's hosted models with a single install command. It offers automatic routing and cost receipts to help teams reduce model costs without changing workflows. If you're looking for alternatives, here are the best options to consider, each with unique strengths in model access, routing, and cost management.
OpenRouter
OpenRouter provides a unified API for hundreds of models from multiple providers, including open and proprietary options. It offers automatic routing based on price or performance, and detailed usage analytics. While it doesn't integrate directly into coding harnesses like Together Link, it's a flexible alternative for teams wanting broad model access and cost optimization.
LiteLLM
LiteLLM is an open-source library that standardizes API calls across 100+ LLMs, including Together AI, OpenAI, and Anthropic. It supports routing, fallbacks, and cost tracking, and can be integrated into custom coding agents. Unlike Together Link, it requires more setup but offers greater customization and self-hosting options.
Portkey
Portkey is an AI gateway that provides unified access to 250+ models, with features like caching, load balancing, and cost controls. It offers observability and guardrails, making it suitable for production teams. While it doesn't plug into coding harnesses out-of-the-box, it can be integrated via API for similar cost-saving benefits.
Helicone
Helicone is an open-source observability platform for LLMs that also offers a gateway for routing and caching. It provides detailed cost tracking and analytics, helping teams reduce expenses. It's a good alternative for those who want to monitor and optimize model usage across various providers, though it lacks direct coding harness integration.
Martian
Martian focuses on intelligent model routing to optimize for cost, quality, and speed. It automatically selects the best model for each request and provides transparency into routing decisions. While it's not specifically designed for coding harnesses, it can be used as a drop-in replacement for model calls to achieve similar cost reductions.
Cloudflare AI Gateway
Cloudflare AI Gateway offers a unified interface to multiple AI providers with caching, rate limiting, and analytics. It's easy to set up and integrates with Cloudflare Workers, making it a solid choice for teams already in the Cloudflare ecosystem. It provides cost insights but lacks the coding harness-specific features of Together Link.
Braintrust Proxy
Braintrust Proxy is part of the Braintrust platform, providing a gateway to various LLMs with caching, logging, and cost tracking. It's designed for evaluation and production monitoring, helping teams optimize model usage. While it requires Braintrust's platform, it's a powerful alternative for teams focused on experimentation and cost management.
Together Link excels at integrating open models directly into coding harnesses with minimal setup and clear cost receipts. However, alternatives like OpenRouter and LiteLLM offer broader model access and customization, while Portkey and Helicone provide robust gateways with observability. Martian and Cloudflare AI Gateway focus on intelligent routing and ease of use, and Braintrust Proxy is ideal for teams needing evaluation tools. The best choice depends on your need for harness integration, model variety, and cost control features.
